Optional lyrics & reference chart

Lyrics / reference chordsFor word-level chord placement, paste timestamped lyrics like [00:12.34]Lyric line. Plain lyrics are shown separately so ChordMate does not guess false chord positions.Pasted reference chords are used to check detection accuracy, trigger a better matching fallback, and correct whole-song semitone drift.Without audio, create a practice draft only.
